Services

T&T Survey provides a wide range of hydrographic and topographic survey services, offering an end-to-end solution from data acquisition to final deliverables. Using the latest ‘state-of-the-art’ positioning and survey technology, we provide our customers with solutions which are tailored specifically to their project’s requirements.

HYDROGRAPHIC SURVEY SERVICES AND SOLUTIONS

We own and operate both offshore and coastal survey vessels which have been designed and built specifically to produce high resolution 3D bathymetry, sidescan sonar, water column and LiDAR data, in real-time, and with little or no post processing.

In addition to providing turnkey hydrographic and topographic survey services, T&T Survey also provides systems integration services, data processing services and specialized hydrographic survey training services.
